Short for Grönholm RX, GRX was established by Marcus Grönholm and joined the World RX fray in 2017, running a single Ford Fiesta for Niclas Grönholm, the two-time FIA World Rally Champion’s son. Trading the Fiesta for a brace of new Hyundai i20s in 2018 and bringing double Euro RX Supercar (now RX1) Champion Timur Timerzyanov into the fold, GRX Taneco Team secured fourth in the Teams’ table – before stepping it up in 2019. 

Despite missing two rounds due to appendicitis, Grönholm wound up fourth in the Drivers’ standings with Timerzyanov just behind in fifth, the pair tallying three wins and seven podiums between them to elevate the Finnish squad to second in the Teams’ classification. Grönholm replicated his fourth-placed championship finish in 2020 as GRX Taneco similarly maintained second spot in the Teams’ rankings.

Fellow Finnish outfit SET Promotion was founded by brothers Jussi and Kalle Pinomäki in 2003 to contest the FIA European Rallycross Championship and various international rally championships. Some of the biggest stars in the sport have cut their teeth with SET, from Andreas Bakkerud and Timerzyanov to Reinis Nitišs and Joni Wiman.

The team has won nine European titles to-date, notably clinching the Super1600 (now RX3) crown with Bakkerud in 2011 and 2012, Nitišs in 2013 and Jānis Baumanis in 2015, and adding Supercar honours with Nitišs in 2018.

A single Hyundai was fielded under the GRX-SET banner in selected rounds of World RX in 2019, with Nitišs ascending the podium in Sweden. Krisztián Szabó and Juha Rytkönen were then entered at alternate events in 2020, with the latter racing to the rostrum on his debut on home soil at Kouvola. Szabó partners Grönholm in the renamed GRX-SET World RX Team in 2021.
